Yes, you are right about raw diet - I tried the conversion many years ago though Simba, has 3 teeth - 1 front on top, 1 front on bottom and 1 right side!!!
(He had cogential gum disease as a kitten when I adopted him)

He can not chew, so that's why I started again w/ground raw turkey, and a little ground beef. He immediately gets diahhrea, though, so the quantities now are small.
